We're dividing 348449 by 88 
The aim is to understand the frequency of 88 in 348449.

Step 1:
88 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 88

Moving on to step 2:
88 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 88

On to step 3:
If we divide 348 by 88, we get 3 and a remainder of 84.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 264 from 348, we get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 88

Moving on to step 4:
844 divided by 88 is 9 with a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 792 from 844 to get 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 88

Step 5:
If we divide 524 by 88, we get 5 and a remainder of 84.
The next digit of our result is 5. 
Result so far: 395.0
The remainder is 84 after subtracting 440 from 524.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 88

Let's proceed to step 6:
88 goes into 849 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 3959.0
If we subtract 792 from 849, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
If we divide 570 by 88, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 3959.6
Subtracting 528 from 570 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
88 can be fit into 420 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 3959.64
Subtract 352 from 420 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
88 can be fit into 680 7 times, resulting in a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 3959.647
The remainder is 64 after subtracting 616 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 88 fits into 640 7 times, leaving a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 3959.6477
Subtract 616 from 640 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 3959.6477, with a leftover of 0.00024.
